The bases of a trapezoid are...

• perpendicular

• parallel

• intersecting

Perpendicular lines... (choose the best answer)

• go on forever and ever without touching

• intersect at a right angle

• cross each other

The formula for finding the area of a triangle is...

• b x h

• b + h

• b x h/2

• l x w

The formula for finding the area of a trapezoid is...

• (b1 + b2) x h/2

• 1/2(b1 + b2) x h

• 1/2h x (b1 + b2)

• All of these are correct
